Unit sales
Unit sales explained: what counts as a unit, and what does not
Unit sales is the number of vehicles a dealership delivers in a period, counted in vehicles rather than in revenue. It is the volume side of dealership profit: unit sales multiplied by gross profit per unit gives the total gross the store has to cover its expenses with.
Dealers say units, volume, or deliveries. In the UK and much of Europe the market-level figure is quoted as registrations rather than sales, which is a different measurement and worth keeping separate.
How are unit sales counted?
Unit sales equals the count of vehicles delivered in the period. The complexity is entirely in what you include:
- Retail units. Sold to a consumer or a small business. This is the number that belongs in a PVR calculation.
- Fleet units. Sold in volume to a company or rental buyer, usually at thin margin. Included in departmental volume, excluded from most performance benchmarks.
- Wholesale units. Sold to another dealer or into auction. These are disposals rather than sales, and mixing them into unit sales distorts every per-unit metric downstream.
- Demonstrators and courtesy cars. Counted when they are retailed out, not when they are put into service.
The timing rule matters as much as the inclusion rule. Most stores count a unit when it is delivered rather than when the order is signed, so a strong order-take month can report as a weak sales month.
Unit sales: a worked example
A store writes 132 deals in March. Eight are wholesale disposals to another dealer, six are fleet, and four signed orders are still awaiting delivery at month end. Retail unit sales are 114.
At a gross profit per unit of $3,600, those 114 units produce $410,400 of total gross. Report all 132 instead and PVR appears to fall to $3,110, while the store has actually earned exactly the same money.
What normal volume looks like
- Per dealership, per quarter. The Q2 2026 Presidio-NCM Average Dealership Performance Benchmark recorded 228 new vehicles and 184 used vehicles retailed at the average US franchised dealership in the quarter, on average revenue of $22.7 million.
- Per dealership, per year. NADA Data 2025 put the average franchised dealership at 955 new vehicles sold across the year, at an average retail selling price of $48,205. The 16,990 US franchised light-vehicle dealers sold 16.2 million light-duty vehicles between them, and franchised stores retailed 13.1 million used vehicles at an average of $28,680.
- Per salesperson. NADA's productivity guide sets the expectation at 12 to 15 units per month, and NADA Data recorded an average of 114 new retail units per new-vehicle salesperson and 139 per used-vehicle salesperson across 2025.
Unit sales versus registrations
Outside the US the headline market number is usually registrations, which counts vehicles put on the road rather than deals closed at a dealership. The SMMT reported 2,020,520 new car registrations in the UK in 2025, up 3.5% year on year, with 779,587 of those going to private buyers, or 38.6% of the market.
Registrations and retail unit sales are not interchangeable. A self-registered demonstrator counts as a registration on the day it is plated, and as a unit sale months later when it is retailed. Benchmark your store against a national registration figure without adjusting for that and you will reach the wrong conclusion.
Why unit sales alone is a poor scorecard
- Volume bought with gross is not growth. Extra units at a discount can hold volume steady while total gross falls. Track it against gross profit per unit.
- Mix moves the number. NADA Data recorded light-duty trucks at 83.0% of new light-duty sales in 2025. A shift in mix changes revenue and gross far more than it changes the unit count.
- Volume sets the stock plan. Your sales rate is the denominator in days supply, so an unstable unit count makes every inventory decision harder.
- New and used behave differently. NADA's guide sets a used-to-new retail ratio target of 1.25 to 1, which plenty of stores never look at.
Read unit sales as one half of a multiplication, never as the answer on its own. Volume times gross is the number that pays the bills.
